Evaluation of WhatsApp web accessibility from the perspective of users with moderate deafness

Abstract

The qualitative methodology used in this research included techniques such as direct observation of interfaces during the execution of tasks, using the Cognitive Path method. This process identified five significant errors that affect the experience of users with moderate deafness when using WhatsApp Web. These errors highlight the need to improve the clarity of visual elements and interface interactions, such as icons, buttons and status settings, to make them more understandable and intuitive. In response to these challenges, five improvement recommendations were developed, materialized in prototypes of new windows. These suggestions represent important contributions from the research, aiming to improve accessibility and ensure that the application offers a more satisfactory experience for users with moderate deafness. Specifically, significant barriers were observed for users with moderate deafness, changes were proposed aimed at improving the usability and visual clarity of the application, offering the necessary adjustments for communication.
